The 1964 Studebaker Daytona gained a four-door sedan in addition to the station wagon and convertible offered on the six-cylinder line. The first series eight-cylinder models included the body styles from the six-cylinder line and added a 2-door hardtop with seating for six passengers. The Lark name had become de-emphasized except for the early Commander and Challenger models. The Commander models had replaced the 1963 Regal line, while the Challenger replaced the 1963 Standard line.
The Daytona had wide side moldings, dual headlights, and 'Daytona' identification on the front fenders. Power was from an overhead-valve six-cylinder engine displacing 169.6 cubic inches and offering 112 horsepower. The V8 version displaced 259.2 cubic inches and had 180 horsepower. Exteriorly, the Six- and Eight-cylinder models were similar with the eights having '8' emblems on the front fenders. The sedan and hardtop body styles had crossed checkered flag V-8 emblems located on the upper rear quarter panels.
